The Quick Read: Divide what a similar property would earn on a standard monthly lease by the full monthly obligation (principal, interest, taxes, insurance, and association dues), then compare that ratio with the program floor, because many DSCR files fall back to that number when short-term income is not accepted.
- A long-term-rent ratio at or above the program floor means a low appraisal cannot sink the file.
- A ratio below the floor means the file depends on the lender accepting your short-term income.
- Stress the payment side too, since taxes, insurance, and dues can move after you buy.
- Passing the lender’s test does not mean the property makes money.
Why Would a DSCR Lender Look at Long-Term Rent on an Airbnb?
Because the appraisal that comes with a DSCR file usually includes a long-term rent estimate, and some programs use that number instead of your Airbnb income. Across the wholesale network Lendmire works with, programs split into those that accept short-term income and those that qualify only on market rent.

As of Oct 15, 2026 · General Freddie Mac market benchmark, not a Lendmire loan offer. Nightly rate, occupancy, taxes, and insurance are editable estimates. Qualifying income for short-term rentals varies by program — some use appraisal market rent, others use documented STR history or projections — and is confirmed in underwriting. Not a Loan Estimate, approval, or commitment to lend. Program availability and eligibility are subject to lender guidelines, credit approval, property review, and underwriting.
The estimate comes from a rent schedule, called Form 1007 on a single-family home and Form 1025 on a two-to-four-unit building. Class Valuation, an appraisal-management firm, says the 1007 was built only to estimate long-term monthly rent. It also notes that private lending is not bound by agency eligibility rules, so each lender decides how much weight that form carries.
The gap matters because a well-run Airbnb often earns more than the same house would on a twelve-month lease. When a lender uses the lease-based number, that gap becomes a lower ratio. Lenders usually count short-term income in one of three ways:
| Method | Built from | Relative conservatism |
|---|---|---|
| Documented history | Platform statements or manager reports | Moderate |
| Third-party projection | Market-data report for the area | Varies by lender |
| Long-term market rent | Appraiser’s rent schedule | Most conservative |
Most programs we place files with use one of these as the main path and keep the lease-based number as a reference. A few use whichever is lower. You rarely know which until you ask, so you test the lowest one first.
Key Terms Defined
DSCR (debt service coverage ratio): Monthly rental income divided by the monthly housing obligation. It shows whether rent covers the loan.
PITIA: Principal, interest, taxes, insurance, and association dues. It is the bottom half of the DSCR fraction.
Appraiser rent schedule: The appraiser’s estimate of what the property would rent for on a standard long-term lease.
Haircut (expense factor): A percentage a lender subtracts from gross short-term income before counting it. Lenders apply different percentages.
Break-even rent: The lowest monthly rent that brings coverage up to the program floor.
Coverage floor: The lowest DSCR a program accepts. Floors differ by program and by purchase versus refinance.
The Five-Step Stress Test
Run the test in this order, using only monthly figures: get the payment, build a rent range, compute coverage, compute break-even rent, then compare with the floor. Each step takes a few minutes with a calculator and a rental search, and it shows you the worst number a lender could use.
1. Get the full monthly obligation. Add up principal, interest, taxes, insurance, and association dues. Use a real insurance quote, not a guess. Insurance on a short-term rental is often priced differently from a standard landlord policy.
2. Build a long-term rent range. Pull comparable rentals that are leased on monthly terms, in the same area and size. Do not multiply a nightly price by thirty. HousingWire reports that appraisers have been told that shortcut is not valid, and a lender will not accept it either. Build a low, middle, and high figure instead of one.
3. Divide. Take each rent figure and divide it by the monthly obligation. The low figure is your stress case.
4. Find break-even rent. Multiply the monthly obligation by the program floor. That is the rent you need. Then ask how far it sits above your low estimate.
5. Compare with the floor. Use the floor for your actual transaction. The next section covers what select programs in the network expect.
Keep the ratio on one definition throughout. Some analysts divide net operating income by debt payments, which is a different calculation. A residential DSCR file typically divides rent by PITIA, and the two results cannot be compared.
The Program Numbers to Test Against
On short-term rental files, the network’s select programs typically allow leverage up to 75% LTV on a purchase and up to 70% on a refinance. On cash-out, the ceiling is typically 70% on short-term-rental collateral, versus 75% on standard rentals. Most programs expect a credit score of about 640 or higher and around twelve months of hosting or landlord experience.
The coverage floor is 1.00 on a purchase and 1.00 on a refinance, as separate program rules. Market commentary reports that many lenders ask for at least 1.1, according to HousingWire. In the network, 1.00 is where select programs start. Stronger ratios can open better pricing and leverage.
Loan sizes on standard programs run up to $3,000,000. Reserves vary by lender, leverage, loan size, and transaction type, and are commonly around six months of PITIA. All of this is subject to lender guidelines and individual underwriting, and none of it is a commitment to lend.

A Worked Example With Modeled Numbers
Take one hypothetical property and one monthly obligation. These ratios are modeled assumptions, not market data. Any calculator shown on this page is a separate, editable, illustrative estimate with its own inputs, so its revenue and cash-flow outputs will not match these modeled ratios and should not be read as the same scenario.
- Using full documented short-term income, coverage comes out at about 1.35x.
- Using short-term income after a lender haircut, it comes out near 1.15x.
- Using only the appraiser’s long-term rent, it comes out at about 0.95x.
The same house passes on two bases and misses on the third. At 0.95x, long-term rent would need to rise about 5% to reach 1.00. That is break-even rent, and it is a small gap that a single appraisal can easily open.
Now raise the monthly obligation by 10% to model higher taxes or insurance. The long-term ratio falls to about 0.86x, and break-even rent moves to roughly 16% above your long-term estimate. The short-term-income ratio drops from 1.35x to about 1.23x, which still clears the floor.
One more lever is the rent estimate. If the appraiser’s number lands 10% below your middle estimate, the 0.95x ratio becomes about 0.86x. Always test a rent range, not a single figure.
The Stress Grid
A grid shows income and payment pressure at the same time. Rows are the income bases a lender might use, and columns are the monthly obligation as modeled, up 10%, and up 20%. Each cell is checked against a 1.00 floor.
| Income basis | As modeled | Obligation +10% | Obligation +20% |
|---|---|---|---|
| Full STR income | 1.35x pass | 1.23x pass | 1.13x pass |
| STR after haircut | 1.15x pass | 1.05x pass | 0.96x miss |
| Long-term rent only | 0.95x miss | 0.86x miss | 0.79x miss |
Read the grid for patterns. If the whole bottom row misses, the file depends on short-term income being accepted. If the middle row falls below the floor at +20%, a haircut plus a bad insurance renewal breaks the deal. Build your own version with your real numbers and your real floor.
Coverage Is Not Cash Flow
Clearing the floor means rent covers PITIA. It does not mean you are making money. DSCR compares rent to PITIA only, so repairs, vacancy, management, utilities, supplies, and big-ticket replacements all sit outside the ratio.
Picture a property that clears 1.20x on a lender’s test. In a slow quarter, with cleaning, utilities, and a manager’s fee paid, the owner can still be losing money that month. The lender’s test and your own budget are different tools.
So run a second, private test. Take your slowest quarter of expected bookings, subtract every operating cost, and see what is left. Tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.
What If the Test Fails?
A failed test is information, not a verdict. Each fix changes the ratio in a different way and carries its own trade-off.
| Remedy | What it changes | Trade-off |
|---|---|---|
| Larger down payment | Lowers the obligation | More cash in; caps still apply |
| Negotiate the price | Lowers the obligation | Seller must agree |
| Sub-1.00 program | Changes the floor | Leverage and terms adjusted |
| Interest-only period | Lowers the early obligation | Balance does not fall |
| Longer term | Lowers the obligation | More interest over time |
| Walk away | Nothing | You keep your capital |
A bigger down payment helps, but only so far. Dropping leverage from 75% to 70% cuts the loan balance by about 6.7%. That lifts coverage modestly, because taxes and insurance do not shrink with the loan. It also never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests, enough equity and enough rental coverage.
Coverage below 1.00 is available through select lenders in the network, with leverage and terms adjusted. Interest-only periods and 40-year terms are also available through select lenders. Whether any of these fit depends on credit, reserves, property, and lender review.
DSCR vs. conventional financing
There are two common ways to finance an investment property, and they qualify you differently — here’s how investors weigh them.
Why investors choose it
- Qualifies on the property’s rental income — no personal tax returns, W-2s, or pay stubs needed to document income.
- No personal debt-to-income ceiling to clear, so existing mortgages and obligations don’t cap your borrowing the same way.
- Can be closed in an LLC, keeping the property inside a business entity.
- Built for scaling — not held to the limit on number of financed properties that conventional financing applies.
- Underwriting centers on the deal: generally qualifies when the rent covers the payment, a 1.00x coverage ratio being a common baseline (confirmed in underwriting).
- Designed specifically for investment property, including long-term and, where the program allows, short-term rentals.
Where it’s strong
- Often the lowest ongoing financing cost for a buyer who fully qualifies on personal income — a fit for a first property or a cost-first purchase.
Trade-offs for investors
- Requires full personal income documentation and must fit within a debt-to-income limit — salary, existing debts, and other mortgages all count.
- Typically held in your personal name rather than a business entity.
- Caps how many financed properties you can carry, which can become a ceiling as a portfolio grows.
- Evaluates you as a borrower as much as the property, which usually means more paperwork.
How investors usually choose: a first or single property often optimizes for the lowest financing cost; portfolio builders often optimize for leverage, vesting in an LLC, and scaling past conventional caps. The right answer depends on your goals, the property, and current guidelines — both paths run through select lenders in Lendmire’s wholesale network, with eligibility and terms confirmed in underwriting.
Where the Rule Breaks
Several situations change the picture, and a few can make the test moot.
Legal use. Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income. If the property cannot legally be used that way, short-term income may not count at all.
No hosting history. Programs that value history want about twelve months. A brand-new purchase has none, which pushes the file toward a projection or the long-term number. This is why the stress test matters most on first-time Airbnb purchases.
A low appraisal. Some channels use only the appraiser’s figure. Others allow a variance supported by a current lease. Ask which applies before you order the appraisal.
Appraiser reluctance. HousingWire reports that appraisers are encouraged to decline an assignment that asks them to repurpose the 1007 for short-term analysis. The practical result is that you may get a conservative long-term figure with little room to argue.
Agency contrast. HousingWire also reports that Fannie Mae policy leaders have said the 1007 is not designed to support short-term income. That is an agency view and does not govern DSCR files. It does show why the form produces a number below what a strong Airbnb earns.
Seasonality. An annual average can hide a weak season. If the property has a heavy peak, test the slow months on their own, and keep extra margin above the floor.
Property type. Manufactured homes, log homes, and barndominiums are not offered through the network’s DSCR programs, so no stress test can fix them.
If a denial has already happened, Lendmire has a separate piece DSCR Loan Denied Because The Appraiser Used Long-term Rent Instead Of Airbnb Income.
When to Run the Test
Run it before you make an offer, not after the appraisal. The worst time to learn the long-term ratio is after you are under contract. At that point your leverage with the seller is gone and your deposit may be at risk.
A sensible order looks like this:
1. Before the offer, run the five steps with low, middle, and high rent figures.
2. Before the appraisal is ordered, ask which income basis the lender will use and what happens if the rent schedule comes back low.
3. After the appraisal, rerun the ratio with the real number and the real insurance quote.
If you own a long-term rental and plan to convert it, the same timing logic applies.

Frequently Asked Questions
Does the lender always use long-term rent on an Airbnb?
No. Some programs accept short-term income through documented history or a projection, and others qualify only on market rent. Many use the lease-based number as a fallback or as a cap. Ask which basis your lender uses and what happens if the appraisal disagrees with your numbers.
Can I still qualify if the long-term test fails?
Possibly, depending on the program. If the lender accepts short-term income, a failed long-term ratio may not decide the file. Coverage below 1.00 is also available through select lenders in the network, with leverage and terms adjusted. Eligibility rests on lender guidelines, credit, reserves, and property review.
How do I estimate what the appraiser will use?
Pull comparable rentals leased on monthly terms, matching size, condition, and location. Build a low, middle, and high figure. Avoid multiplying a nightly price by thirty. Then expect the appraiser’s number to land closer to the low end than the high end.
What about a mid-term rental as a fallback?
It can be a useful downside plan, but a lender still works from its own income rules and the appraisal. Treat mid-term income as part of your private cash-flow planning, not as a figure the lender will necessarily count. Confirm the treatment before you rely on it.
Does clearing the ratio mean the property is profitable?
No. The ratio compares rent to PITIA only. Repairs, vacancy, management, utilities, and big-ticket replacements sit outside it. A property can clear the floor and still lose money in a slow month, so run your own budget alongside the lender’s test.
